Abstract

Chondromyxoid fibroma is an uncommon benign cartilaginous tumor accounting for less than 1% of all bone tumors. The classic site of involvement is the metaphyseal region of long tubular bones, usually presenting in the second to third decades of life with nonspecific pain and swelling of the affected part. This case is an interesting incidental finding in a juvenile hallux abductovalgus deformity with no prodrome, eccentrically located in the diaphysis of the first metatarsal. Early detection and complete surgical resection are valuable in preventing recurrence in the affected bone. ACFAS Level of Clinical Evidence: 4.
